+  DuckDB is an in-process SQL OLAP database management system designed for analytical query processing.
+---
+
+## About
+
+[DuckDB](https://duckdb.org/) is an embedded analytical database management system that runs in-process with the client application. It is optimized for analytical workloads, providing high performance for complex queries with minimal setup.
+
+DuckDB has the following notable characteristics:
+
+- In-process, serverless database engine
+- Supports complex SQL queries for analytical processing
+- Can operate on in-memory or persistent storage
+- Zero-configuration - no external dependencies or server setup required
+- Highly optimized for columnar data storage and query execution
+
+For more details, refer to the [DuckDB Documentation](https://duckdb.org/).
+
+## Available Tools
+- [`duckdb-sql`](../tools/duckdb/duckdb-sql.md)  
+  Execute pre-defined prepared SQL queries in DuckDB.
+  
+## Requirements
+
+### Database File
+
+To use DuckDB, you can either:
+
+- Specify a file path for a persistent database stored on the filesystem
+- Omit the file path to use an in-memory database
+
+## Example
+
+For a persistent DuckDB database:
+
+```yaml
+sources:
+    my-duckdb:
+        kind: "duckdb"
+        dbFilePath: "/path/to/database.db"
+        configuration:
+            memory_limit: "2GB"
+            threads: "4"
+```
+
+For an in-memory DuckDB database:
+
+```yaml
+sources:
+    my-duckdb-memory:
+        name: "my-duckdb-memory"
+        kind: "duckdb"
+```

+---
+
+## About
+
+A `duckdb-sql` tool executes a pre-defined SQL statement against a [DuckDB](https://duckdb.org/) database. It is compatible with any DuckDB source configuration as defined in the [DuckDB source documentation](../../sources/duckdb.md).
+
+The specified SQL statement is executed as a prepared statement, and parameters are inserted according to their position: e.g., `$1` is the first parameter, `$2` is the second, and so on. If template parameters are included, they are resolved before execution of the prepared statement. 
+
+DuckDB's SQL dialect closely follows the conventions of the PostgreSQL dialect, with a few exceptions listed in the [DuckDB PostgreSQL Compatibility documentation](https://duckdb.org/docs/stable/sql/dialect/postgresql_compatibility.html). For an introduction to DuckDB's SQL dialect, refer to the [DuckDB SQL Introduction](https://duckdb.org/docs/stable/sql/introduction).
+
+### Concepts
+
+DuckDB is a relational database management system (RDBMS). Data is stored in relations (tables), where each table is a named collection of rows. Each row in a table has the same set of named columns, each with a specific data type. Tables are stored within schemas, and a collection of schemas constitutes the entire database.
+
+For more details, see the [DuckDB SQL Introduction](https://duckdb.org/docs/stable/sql/introduction).
+
+## Example
+
+> **Note:** This tool uses parameterized queries to prevent SQL injections. Query parameters can be used as substitutes for arbitrary expressions but cannot be used for identifiers, column names, table names, or other parts of the query.
+
+```yaml
+tools:
+  search-users:
+    kind: duckdb-sql
+    source: my-duckdb
+    description: Search users by name and age
+    statement: SELECT * FROM users WHERE name LIKE $1 AND age >= $2
+    parameters:
+      - name: name
+        type: string
+        description: The name to search for
+      - name: min_age
+        type: integer
+        description: Minimum age
+```
+
+## Example with Template Parameters
+
+> **Note:** Template parameters allow direct modifications to the SQL statement, including identifiers, column names, and table names, which makes them more vulnerable to SQL injections. Using basic parameters (see above) is recommended for performance and safety. For more details, see the [templateParameters](../#template-parameters) section.
+
+```yaml
+tools:
+  list_table:
+    kind: duckdb-sql
+    source: my-duckdb
+    statement: |
+      SELECT * FROM {{.tableName}};
+    description: |
+      Use this tool to list all information from a specific table.
+      Example:
+      {{
+          "tableName": "flights",
+      }}
+    templateParameters:
+      - name: tableName
+        type: string
+        description: Table to select from

+description: >
+  How to get started running Toolbox with MCP Inspector and AlloyDB as the source.
+---
+
+## Overview
+
+[Model Context Protocol](https://modelcontextprotocol.io) is an open protocol
+that standardizes how applications provide context to LLMs. Check out this page
+on how to [connect to Toolbox via MCP](../../how-to/connect_via_mcp.md).
+
+## Before you begin
+
+This guide assumes you have already done the following:
+
+1.  [Create a AlloyDB cluster and instance](https://cloud.google.com/alloydb/docs/cluster-create) with a database and user.
+1. Connect to the instance using [AlloyDB Studio](https://cloud.google.com/alloydb/docs/manage-data-using-studio), [`psql` command-line tool](https://www.postgresql.org/download/), or any other PostgreSQL client.
+
+2.  Enable the `pgvector` and `google_ml_integration` [extensions](https://cloud.google.com/alloydb/docs/ai). These are required for Semantic Search and Natural Language to SQL tools. Run the following SQL commands:
+
+    ```sql
+    CREATE EXTENSION IF NOT EXISTS "vector";
+    CREATE EXTENSION IF NOT EXISTS "google_ml_integration";
+    CREATE EXTENSION IF NOT EXISTS alloydb_ai_nl cascade;
+    CREATE EXTENSION IF NOT EXISTS parameterized_views;
+    ```
+
+## Step 1: Set up your AlloyDB database
+
+In this section, we will create the necessary tables and functions in your AlloyDB instance.
+
+1.  Create tables using the following commands:
+
+    ```sql
+    CREATE TABLE products (
+      product_id SERIAL PRIMARY KEY,
+      name VARCHAR(255) NOT NULL,
+      description TEXT,
+      price DECIMAL(10, 2) NOT NULL,
+      category_id INT,
+      embedding vector(3072) -- Vector size for model(gemini-embedding-001)
+    );
+
+    CREATE TABLE customers (
+      customer_id SERIAL PRIMARY KEY,
+      name VARCHAR(255) NOT NULL,
+      email VARCHAR(255) UNIQUE NOT NULL
+    );
+
+    CREATE TABLE cart (
+      cart_id SERIAL PRIMARY KEY,
+      customer_id INT UNIQUE NOT NULL,
+      created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP,
+      FOREIGN KEY (customer_id) REFERENCES customers(customer_id)
+    );
+
+    CREATE TABLE cart_items (
+      cart_item_id SERIAL PRIMARY KEY,
+      cart_id INT NOT NULL,
+      product_id INT NOT NULL,
+      quantity INT NOT NULL,
+      price DECIMAL(10, 2) NOT NULL,
+      FOREIGN KEY (cart_id) REFERENCES cart(cart_id),
+      FOREIGN KEY (product_id) REFERENCES products(product_id)
+    );
+
+    CREATE TABLE categories (
+      category_id SERIAL PRIMARY KEY,
+      name VARCHAR(255) NOT NULL
+    );
+    ```
+
+2.  Insert sample data into the tables:
+
+    ```sql
+    INSERT INTO categories (category_id, name) VALUES
+    (1, 'Flowers'),
+    (2, 'Vases');
+
+    INSERT INTO products (product_id, name, description, price, category_id, embedding) VALUES
+    (1, 'Rose', 'A beautiful red rose', 2.50, 1, embedding('gemini-embedding-001', 'A beautiful red rose')),
+    (2, 'Tulip', 'A colorful tulip', 1.50, 1, embedding('gemini-embedding-001', 'A colorful tulip')),
+    (3, 'Glass Vase', 'A transparent glass vase', 10.00, 2, embedding('gemini-embedding-001', 'A transparent glass vase')),
+    (4, 'Ceramic Vase', 'A handmade ceramic vase', 15.00, 2, embedding('gemini-embedding-001', 'A handmade ceramic vase'));
+
+    INSERT INTO customers (customer_id, name, email) VALUES
+    (1, 'John Doe', 'john.doe@example.com'),
+    (2, 'Jane Smith', 'jane.smith@example.com');
+
+    INSERT INTO cart (cart_id, customer_id) VALUES
+    (1, 1),
+    (2, 2);
+
+    INSERT INTO cart_items (cart_id, product_id, quantity, price) VALUES
+    (1, 1, 2, 2.50),
+    (1, 3, 1, 10.00),
+    (2, 2, 5, 1.50);
+    ```
+
+## Step 2: Install Toolbox
+
+In this section, we will download and install the Toolbox binary.
+
+1. Download the latest version of Toolbox as a binary:
+
+    {{< notice tip >}}
+   Select the
+   [correct binary](https://github.com/googleapis/genai-toolbox/releases)
+   corresponding to your OS and CPU architecture.
+    {{< /notice >}}
+    <!-- {x-release-please-start-version} -->
+    ```bash
+    export OS="linux/amd64" # one of linux/amd64, darwin/arm64, darwin/amd64, or windows/amd64
+    export VERSION="0.10.0"
+    curl -O https://storage.googleapis.com/genai-toolbox/v$VERSION/$OS/toolbox
+    ```
+    <!-- {x-release-please-end} -->
+
+1. Make the binary executable:
+
+    ```bash
+    chmod +x toolbox
+    ```
+
+## Step 3: Configure the tools
+
+Create a `tools.yaml` file and add the following content. You must replace the placeholders with your actual AlloyDB configuration.
+
+First, define the data source for your tools. This tells Toolbox how to connect to your AlloyDB instance.
+
+```yaml
+sources:
+  alloydb-pg-source:
+    kind: alloydb-postgres
+    project: YOUR_PROJECT_ID
+    region: YOUR_REGION
+    cluster: YOUR_CLUSTER
+    instance: YOUR_INSTANCE
+    database: YOUR_DATABASE
+    user: YOUR_USER
+    password: YOUR_PASSWORD
+```
+
+Next, define the tools the agent can use. We will categorize them into three types:
+
+### 1. Structured Queries Tools
+
+These tools execute predefined SQL statements. They are ideal for common, structured queries like managing a shopping cart. Add the following to your `tools.yaml` file:
+
+```yaml
+tools:
+
+  access-cart-information:
+    kind: postgres-sql
+    source: alloydb-pg-source
+    description: >-
+      List items in customer cart.
+      Use this tool to list items in a customer cart. This tool requires the cart ID.
+    parameters:
+      - name: cart_id
+        type: integer
+        description: The id of the cart.
+    statement: |
+      SELECT
+        p.name AS product_name,
+        ci.quantity,
+        ci.price AS item_price,
+        (ci.quantity * ci.price) AS total_item_price,
+        c.created_at AS cart_created_at,
+        ci.product_id AS product_id
+      FROM
+        cart_items ci JOIN cart c ON ci.cart_id = c.cart_id
+        JOIN products p ON ci.product_id = p.product_id
+      WHERE
+        c.cart_id = $1;
+
+  add-to-cart:
+    kind: postgres-sql
+    source: alloydb-pg-source
+    description: >-
+      Add items to customer cart using the product ID and product prices from the product list.
+      Use this tool to add items to a customer cart.
+      This tool requires the cart ID, product ID, quantity, and price.
+    parameters:
+      - name: cart_id
+        type: integer
+        description: The id of the cart.
+      - name: product_id
+        type: integer
+        description: The id of the product.
+      - name: quantity
+        type: integer
+        description: The quantity of items to add.
+      - name: price
+        type: float
+        description: The price of items to add.
+    statement: |
+      INSERT INTO
+        cart_items (cart_id, product_id, quantity, price)
+      VALUES($1,$2,$3,$4);
+
+  delete-from-cart:
+    kind: postgres-sql
+    source: alloydb-pg-source
+    description: >-
+      Remove products from customer cart.
+      Use this tool to remove products from a customer cart.
+      This tool requires the cart ID and product ID.
+    parameters:
+      - name: cart_id
+        type: integer
+        description: The id of the cart.
+      - name: product_id
+        type: integer
+        description: The id of the product.
+    statement: |
+      DELETE FROM
+        cart_items
+      WHERE
+        cart_id = $1 AND product_id = $2;
+```
+
+### 2. Semantic Search Tools
+
+These tools use vector embeddings to find the most relevant results based on the meaning of a user's query, rather than just keywords. Append the following tools to the `tools` section in your `tools.yaml`:
+
+```yaml
+  search-product-recommendations:
+    kind: postgres-sql
+    source: alloydb-pg-source
+    description: >-
+      Search for products based on user needs.
+      Use this tool to search for products. This tool requires the user's needs.
+    parameters:
+      - name: query
+        type: string
+        description: The product characteristics
+    statement: |
+      SELECT
+        product_id,
+        name,
+        description,
+        ROUND(CAST(price AS numeric), 2) as price
+      FROM
+        products
+      ORDER BY
+        embedding('gemini-embedding-001', $1)::vector <=> embedding
+      LIMIT 5;
+```
+
+### 3. Natural Language to SQL (NL2SQL) Tools
+
+1. Create a [natural language configuration](https://cloud.google.com/alloydb/docs/ai/use-natural-language-generate-sql-queries#create-config) for your AlloyDB cluster.
+
+    {{< notice tip >}}Before using NL2SQL tools,
+    you must first install the `alloydb_ai_nl` extension and
+    create the [semantic layer](https://cloud.google.com/alloydb/docs/ai/natural-language-overview) under a configuration named `flower_shop`.
+    {{< /notice >}}
+
+2. Configure your NL2SQL tool to use your configuration. These tools translate natural language questions into SQL queries, allowing users to interact with the database conversationally. Append the following tool to the `tools` section:
+
+```yaml
+  ask-questions-about-products:
+    kind: alloydb-ai-nl
+    source: alloydb-pg-source
+    nlConfig: flower_shop
+    description: >-
+      Ask questions related to products or brands.
+      Use this tool to ask questions about products or brands.
+      Always SELECT the IDs of objects when generating queries.
+```
+
+Finally, group the tools into a `toolset` to make them available to the model. Add the following to the end of your `tools.yaml` file:
+
+```yaml
+toolsets:
+  flower_shop:
+    - access-cart-information
+    - search-product-recommendations
+    - ask-questions-about-products
+    - add-to-cart
+    - delete-from-cart
+```
+
+For more info on tools, check out the
+[Tools](../../resources/tools/) section.
+
+## Step 4: Run the Toolbox server
+
+Run the Toolbox server, pointing to the `tools.yaml` file created earlier:
+
+```bash
+./toolbox --tools-file "tools.yaml"
+```
+
+## Step 5: Connect to MCP Inspector
+
+1. Run the MCP Inspector:
+
+    ```bash
+    npx @modelcontextprotocol/inspector
+    ```
+
+1. Type `y` when it asks to install the inspector package.
+
+1. It should show the following when the MCP Inspector is up and running (please take note of `<YOUR_SESSION_TOKEN>`):
+
+    ```bash
+    Starting MCP inspector...
+    ⚙️ Proxy server listening on localhost:6277
+    🔑 Session token: <YOUR_SESSION_TOKEN>
+       Use this token to authenticate requests or set DANGEROUSLY_OMIT_AUTH=true to disable auth
+
+    🚀 MCP Inspector is up and running at:
+       http://localhost:6274/?MCP_PROXY_AUTH_TOKEN=<YOUR_SESSION_TOKEN>
+    ```
+
+1. Open the above link in your browser.
+
+1. For `Transport Type`, select `Streamable HTTP`.
+
+1. For `URL`, type in `http://127.0.0.1:5000/mcp`.
+
+1. For `Configuration` -> `Proxy Session Token`, make sure `<YOUR_SESSION_TOKEN>` is present.
+
+1. Click Connect.
+
+1. Select `List Tools`, you will see a list of tools configured in `tools.yaml`.
+
+1. Test out your tools here!
